BOX FOR UPRIGHT SPENDLES.

$PECIPICATION forming part of Letters Patent No, 392,732, dated November 1.3, 1888: application filed July 20, IRES. Serial No. 280,501. (No model.)

E0 M2 whom it may concern:

' Be it known that I, ALFRED l3. HUIOHIN sON, of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Boxes for Upright Spindles of Planing and other Machines, of which the following is a specification, reference being had to the accompanying drawings.

The object of this improvement is to dis pense with caps on the journal-boxes of upright spindles, and to obviate the liability to the binding of the journals of such spindles, which is-liable to occur when boxes are used with caps which require more than one screw to each cap, owing to the difficulty of screwing up all the screws uniformly.

I will now proceed to describe the invention with reference to the drawings,and afterward point out its novel features in claims.

In the drawings, Figure 1 represents a side View,partly in section,of the matcher-leg of a matcherspindle and spindlebox of a wood planing machine embodying my i mprovement; Fig. 2, a plan View of the same, and Fig. 3 a horizontal view on the line 00 0c of Fig. 1.

Like letters of reference indicate corresponding parts in the several drawings.

A indicates an upright spindle having thereon a substantially straight lower journal, a, and a tapered upper journal,b,at a distance above said lower journal.

B designates the matcher -leg or spindleframe, upon which are formed the lower undivided spindle jonrnal-box, D, and the upper undivided spindlejournal-box, G, for journals a and b. V

E indicates an adjustable lower end or spindle foot hearing or step to support the weight of spindle and to adjust the tapered journal I) to its box 0. The adjustable step E is square in horizontal section and is fitted to slide vertically in a guide or socket, g, in the bot tom of box D. Directly beneath the step E and coaxial with spindle A is an adjustingscrew, G, screwed into and through the bottom of box D and against the under side of By turning screw G to the right or left the step, and with it the spindle, is raised or lowered, and thereby the journal Z) may be perfectly adjusted in the box 6, and may be lowered as the bearing-faces wear away, thereby compensating for such wear and re newing the fit of the tapered journal in its seat.

The spindle-frame B represented is intended to be supported by a bar extending across the machine and through the split clamp f.

The part of the spindle A below the tapered journal I) is slightly less in diameter than that employed, dependence must be placed upon the uniform and careful manipulation of the screws in adjusting the caps to the boxes,and thejournals are liable to become bound in the boxes if such adjustment is slightly defective.

By my improvement the use ofsuch caps and bolts is entirely obviated, and the entire adjustment of the spindlebearings is easily and rapidly effected by the single adj ustingscrew G. Y

The step or end bearing, E, is represented as located at a distance below the lower end of journal a, in order that oil from an oil-chain ber, F, may freely reach every part of the wearingsurface of the step or end bearing,and also have free access to the lower end of journal a. The oil-chamber F communicates with the upper part ofjournal a throughapassage, It, provided for that purpose, The screw G and jam-nut It should be carefully fitted, to prevent the leakage of oil.

(2 designates an oil-chamber, and e a tallowchamber, in box 0, for lubricating the journal b and its box C. WVhile the journal is cool, oil only will be consumed in lubrication;

but whenever the oil gives out and the box he comes heated the tallow will melt and maintain the lubrication at the higher temperature.

c is a tallow box or chamber for box D.

The oil-chambers F and (Z and tallow-ehamher 6 are open at the top. Around the top of box 0 an oil cup or basin, Z, is formed, which incloses the spindle, the mouth of the oil-chamber d, and that of the tallow-chamher 0. When the oil cup or basin Z is partially filled with oil, the oil will find its way down between the journal I) and its box, thus insuring the lubrication of that journal. Around the top of box D a similar oil cup or basin, Z, is formed, inclosing the spindle and mouth of oil-chamber F, but excluding the mouth of tallow-chamber c.

For the purpose of facilitating the placing and removal of the step F, and in order that the oil-chamber F, the lower part of box D, and the guide-socket 9 may be emptied of oil and dirt and thoroughly and easily cleaned, I make the bottom of box D removable by making it to consist of a cap, a, which opens and closes the lower end of guide-socket g, and which screws on and off and is carefully fitted to the box to prevent leakage of oil, and I place the screw G in the said cap, fitting into and through the same in line with the axis of the spindle.

In the drawings the boxes C and l) and the adjustable step E are represented as babbitted, or lined or surfaced with an antifriction metal in the usual manner. 0 designates that lining.

\Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with an upright spindle having thereon a substantially straight lower journal anda tapered upper journal at a distance above said lower journal, of a spindle-frame and upper and lower undivided boxes thereon for said j ournals,and an adj ustable step for the foot of the spindle to support the weight of the spindle, and a screw for adjusting the said step and thereby adjusting the tapered journal to its box, substantially as specified.

2. The combination, with an upright spindle having thereon a lowerjournal, of an undivided box for said journal, and an adj ustable step in said box for the foot of the spindle below the journal, an oil chamber within the box for lubricating both the journal and step, a cap forming the bottom of the box and removable for the insertion of the step and cleaning of the box, and an adjusting-screw fitted into and through the cap to raise and lower the step, substantially as specified.
